Consistent ~5% Packet Loss (Connecticut)
I'm a Cox customer living in CT. I have been experiencing packet loss for the past few weeks. It does not appear to be on my end. Below I'll post MTR results (I am pinging a Blizzard game server).
I should mention that this is over a wired connection.

My router does not have any packet loss, but I immediately experience 4% packet loss here at the second hop (not exactly sure where this is). I just want to make sure that my router/modem are not causing any issues. It's possible that this second hop is perhaps in my apartment complex or somewhere nearby, but again, I don't know where all these hops are located.
Most of the evening, I experience this 3-5% packet loss, and it is noticeable, particularly over VoIP (Discord).Strangely enough, I had a ~4 hour window last night with no packet loss, but it came back late last night and is present as I type this post now.
I'm not a network engineer, so perhaps I missed something in the MTR above. Just looking for input so I can better understand the issue.
Thanks,
Ryan

What Cox internet tier are you on? What modem are you using? Just curious.

So, I experienced no packet loss at all during the past weekend (11/30 and 12/1). It was even fine this morning around 6:30 A.M.
However, as of 6:30 P.M. tonight (12/2), it is back to haunt me. I have not made any hardware or firmware changes to spur this on.
While this has occurred on some mornings, it seems to really only be an issue at prime time (evenings). Perhaps there is some sort of localized congestion/traffic. Based on the previous discussion and presented information, it doesn't appear to be any of my equipment. We previously discussed that I do not have any splitters or amplifiers installed.
Below is a fresh WinMTR (again over a hard-wired connection):

Similar to previous experiences, I am experiencing a consistent 3-6% packet loss, starting with the second hop (whatever that is).
Edit: Could this be caused by the cold/stormy weather? Given that it has been somewhat cold the past few weeks, and snowy today, could a connection somewhere to the local node be messed up somehow?

Also, here's another thing I don't understand.
Blizzard offers an internal network diagnostic tool (Looking Glass) that allows you to ping their servers. I consistently get similar results using their own MTR within this tool (see below):

Somehow, this doesn't seem to pick up any of the obvious packet loss I am experiencing. So I don't understand that is happening here.

One last update. Checking the event log of my modem, this event happened at 6:47 P.M. tonight:
What could this mean?
